What role do informational nots play in the NEC?

Informational notes in the NEC (National Electrical Code) serve to provide additional context, guidance, and explanations regarding the requirements found within the code. Their primary function is to assist with the application of rules by helping users understand the intent behind specific regulations or offering practical advice on how to comply with them effectively.

These notes are not legally binding provisions, nor do they modify the existing code rules. Instead, they aim to clarify and educate rather than impose regulatory requirements. By offering insights, these notes can enhance the reader's comprehension and facilitate correct implementation of electrical standards. This understanding is critical for ensuring safety and compliance in electrical installations.
